Feature Description

Fault protection feature: When the product malfunctions, a fault indicator is triggered, and the self-protection function is activated.

Overload Protection Function: Cuts off the overloaded circuit after 3 consecutive seconds of overload to prevent fire due to overload.

Short-circuit protection function: Cuts off the circuit power within 150 microseconds when a protected distribution circuit experiences a short circuit, preventing fires caused by the short circuit.

Real-time current measurement function: Measures the current magnitude in the protected distribution circuit in real time.

Communication Function: Supports connection to electrical fire monitoring equipment for remote monitoring.

Real-time temperature measurement feature: Measures the cable temperature in the protected distribution circuit in real time. If the cable temperature exceeds the set threshold, an alarm message is sent to the host computer, and the alarm status remains active until reset.
